TECHNICAL FIELD

The present invention relates to a mobile terminal such as a portable telephone, a PDA, a music player, and a game machine with a removable face panel, in particular, to a mobile terminal with aroma releasing function using an aromatic substance accommodating face panel.

BACKGROUND ART

A design of a removable face panel used in a portable telephone, a PDA, a music player, a game machine, or the like of the prior art may be changed by being replaced to be visually entertaining. A technique of generating fragrance from the portable telephone has been conventionally proposed. A technique in which an open/close operation of an aroma releasing port is carried out by extension and accommodation of a rod antenna of the portable telephone, where the aroma releasing port is opened to release the fragrance when the rod antenna is extended upward, and the aroma releasing port is closed to prevent fragrance from being released when the rod antenna is accommodated in a main body is disclosed in, for example, Unexamined Japanese Patent Publication No. 2002-76734.

In a folding type portable telephone, a technique in which a small hole opened in a member configuring a hinge mechanism is exposed by opening a lid body thereby diffusing aroma of an aroma member filled inside the member towards a user of the portable telephone is disclosed in, for example, Unexamined Japanese Patent Publication No. 2002-290525, or the like.

Furthermore, a technique having characteristics in that a flow path for flowing fragrance of the aromatic substances from openings of a speaker or a microphone arranged inside a housing is arranged inside the housing, and in that an aroma material is arranged adjacent to a battery to promote an aroma effect by heat generation of the battery is disclosed in, for example, Unexamined Japanese Patent Publication No. 2004-254026, or the like.

However, in the technique disclosed in Unexamined Japanese Patent Publication No. 2002-76734, a structure in that aroma is only released when the rod antenna is extended is convenient in that natural release of aroma can be suppressed, but the operation of extending and accommodating the rod antenna is bothersome. The above structure is often not adopted in recent years with increase terminals in which the antenna is built in the housing with high regard for designability.

In the technique disclosed in Unexamined Japanese Patent Publication No. 2002-290525, a function excelling in operability of controlling aroma with the open/close operation of the hinge is provided, but the fragrance attaches to the inside of the housing by arranging the aroma member inside the hinge, thereby influencing the durability of electronic components to which the components of the aroma member come close.

In the technique disclosed in Unexamined Japanese Patent Publication No. 2004-254026, the fragrance attaches to the inside of the housing by arranging the aroma member adjacent to the battery, thereby influencing the durability of electronic components to which the components of the aroma member come close.

According to the above configuration, the aromatic substances can be released in conjunction with the operation of opening the folding type mobile terminal from the closed state, and the aromatic substances can be prevented from being released in conjunction with the operation of closing the folding type mobile terminal from the opened state.

In a mobile terminal using the aromatic substance accommodating face panel of the present invention, a sounding body is arranged in a housing; an air vibration transmitting hole for transmitting an air vibration of the sounding body is formed on a surface of the housing including the sounding body; an aromatic substance accommodating face panel to be removably attached to the housing is arranged, the aromatic substance accommodating face panel having a hollow structure; an air vibration transmission hole for transmitting the air vibration is formed on the surface facing the housing of the aromatic substance accommodating face panel; an aroma releasing hole for releasing aroma to an external space is formed on the surface opposite to the surface facing the housing; the air vibration transmitting hole of the housing and the air vibration transmission hole for transmitting the air vibration of the aromatic substance accommodating face panel are spatially bonded; and the vibration of the sounding body in the housing is transmitted from the air vibration transmitting hole of the housing to the air vibration transmission hole of the aromatic substance accommodating face panel so that the aroma is released to the external space from the aroma releasing hole of the aromatic substance accommodating face panel.

According to this configuration, the aromatic substances are released in conjunction with the operating state of the sounding body, and the aromatic substances are not released in conjunction with the stopped state of the sounding body.

Therefore, the present invention prevents the body of the housing from being attached with fragrance by placing the aromatic substances inside the face panel to be removably attached to the housing. Different fragrances of the aromatic substances can be enjoyed by replacing the face panel portion. In the folding type mobile terminal, the aromatic substances are released when the housings are opened. Furthermore, in the mobile terminal that utilizes vibration of the sounding body, the aromatic substances are released when the sounding body operates. Thus, the aromatic substances can be released at a more effective timing by controlling the release state of the aromatic substances, and the life span of the aromatic substances can be extended.

As a feature of the configuration, a hole is opened on both the front and the back of face panel 701, and the function of the respective holes on the front and the back are divided to an input side and an output side.

The present invention provides a function of releasing aroma at a predetermined time by driving the sounding body with an alarm timer. FIG. 17 shows a flowchart of setting an alarm timer that releases fragrance. First, a setting of an alarm timer that releases fragrance is selected (step S1). Next, the setting of the alarm time is performed (step S2), and thereafter, setting of whether or not to release fragrance is performed (step S3). In the setting of releasing fragrance, a time to release fragrance is set separate from the alarm time (step S4). The time to release fragrance is branched to setting to a default set in advance (step S5), and setting to other times (step S8). For instance, when the default is set to 30 minutes, a timer for releasing the fragrance is set to thirty minutes before the alarm time. When inputting the set time in step S8 instead of the default, a user can freely set the operation until transitioning to the alarm sound operation from the time of setting. The sound in time of setting to release fragrance uses a frequency of low region that is less likely to be heard by ear of about lower than or equal to 50 Hz.

When generating an alarm sound with the alarm timer etc. of the present invention, one can wake up in a nice smell by operating the sound of low region for strongly generating the aroma at a time before the time set in advance.

In mobile terminals such as the portable telephone including a vibrator etc. for incoming annunciation, even though not premised on the sounding body, the aromatic substance accommodating face panel in which the aroma releasing hole is formed on one surface and the air vibration transmission hole for transmitting air vibration is formed on the other surface may be fixed to the housing to release aroma by picking up vibration of the housing from the air vibration transmission hole.
